Abstract

LA BOMBA TIENE UN PAR DE EMBOLOS DE CIERRES APARTE (80, 84) LOS CUALES ESTAN PREPARADOS PARA SOBRELLEVAR UN MOVIMIENTO AXIAL DE ROTACION, MEDIANTE UNA JUNTA SELLADA (109) QUE ESTA ASOCIADA CON LAS PARTES DE CIERRES (80, 84). LA JUNTA SELLADA (109) INCLUYE UNA LINEA ANULAR (112) DISPUESTA DENTRO DE UNA MUESCA (04) EN UN SELLAJE APARTE (8) Y PROYECTANDOSE DESDE AHI HASTA LA SUPERFICIE CILINDRICA (93) DE LA OTRA PARTE SELLADA (84), UN ANILLO-O FLEXIBLE Y ELASTICO (110), DISPUESTO DENTRO DE LA ENCLAVADURA (94) QUE ESTA EN LA SUPERFICIE CILINDRICA (93) DEL OTRO SELLAJE (84) Y DESDE LA SUPERFICIE (108) DEL OTRO SELLAJE. EL ANILLO-O ES ACOMODABLE EN LA SUPERFICIE RADIAL (93) DEL OTRO SELLAJE (84) Y UNA SUPERFICIE (108) DE LA CAMISA ANULAR (112), QUE ESTA PROYECTADA MAS LEJOS DESDE LA ENCLAVADURA (94) POR MEDIO DE UNA BRECHA (122) ENTRE LAS PARTES DE SELLAJES (80, 84) QUE ESTAN CUBIERTOS POR LA CAMISA (112) Y EN CONTACTO CON LA SUPERFICIE CILINDRICA (93) DEL OTRO SELLAJE (84), DE TAL FORMA QUE EL ANILLO-O ES CAPAZ DE REVOLUCIONARSE LA SUPERFICIE CILINDRICA (93) DEL OTRO SELLAJE (84) Y MOVIENDOSE EN LA SUPERFICIE RADIAL (112B) DE LA LINEA ANULAR (112) ENCIMA DEL MOVIMIENTO DE ROTACION DE LAS PARTES SELLADAS (80, 84), RELATIVAS UNAS CON OTRAS.
